Step 2 To Use an Oscillator or Not...

The first thing you need to do is decide whether to use to use an oscillator. Here is the info to let you make your choice:

Advantages of and Oscillator:

• It is much more accurate and doesn't vary near as much as the internal oscillator. This can make the difference between it working and not.

Disadvantages:

• It adds about 50 cents extra cost.
• It takes up more space.
• It adds slightly more complexity.

I highly recommend you use one, but it is not required. I'll include instructions for both ways.
